WHEEL.

To all 'wi/tom 'it may concern:

Be it known that we, RICHARD "."ilitnrsTn sonY BATEMAN and LoFTUs HANsoN Birra MAN, subjects of the King of Great Britain and Ireland, residing, respectively, at Pottern newton, Leeds, and Hunslet, Leeds, both in the county of York, England, have invented Improvements in or Relating to ldulleys or Vheels, of which the following is a specification.

This invention relates to pulleys or wheels, hereinafter called wheels, and has for object an improved arrangement of springs and devices for absorbing the mechanical shocks and vibrations to which such wheels are subjected, particularly reversing driving wheels and driving pulleys, suitable for shafting, machinery and motors and which revolve at a high speed. .In wheels embodying this invention the construction of such devices is simpler than the devices for like purposes heretofore proposed and the cushioning can be suitably adjusted with ease and facility to produce the best results. For this urpose according to this invention the whee s are constructed as we will now proceed to describe with reference to the accompanying illustrative drawings.

Figure 1 of such drawings is a central vertical section corresponding to the line A, B of Fig. 2, and Fig. 2 is a face view, of a driving gear wheel provided with improved means of absorbing mechanicalshocks and vibrations according to this invention. llig. 3 is a sectional view to a larger scale of part of the apparatus.

a indicates the driving wheel, l; a plate which forms one side thereof and c a marginal flange which with the plate b forms a dish in which the shock absorbing device is placed. The outer periphery of the flange c is formed with teeth d and the inner periphery e thereof is furnished with two lugs 'f the opposite faces g of which are parallel to one another and located a su'flicient distance apart to receive between them a head here inafter referred to.

The boss lt of the wheel is mounted to freely rotate upon a sleeve L that projects inwardly from a driving lever 7c having three arms a, 7 and 8. This lever is rigidly secured on the driving shaft Z by a key m and the arm n thereof, which extends from the sleeve i, terminates in an eye o having a bearing p in which is rigidly secured a stud r by means of Specification of Letters Patent.

Application filed September S, 1908.

Patented April 6, 1909.

Serial No. 452,143.

a nut s, the outer end t of such stud projecting inwardly from the arm at.

a is a pendulum lever which is mounted to freely oscillate on the end t of the stud r and the upper end of which consists of a head o each side w of which is suitably rounded, said head freely fitting between the parallel faces g of the lugs f of the driving wheel.

rlhe part oi' the pendulum lever u below the pivot stud t is formed with a llanged oblong opening y of the shape shown and of sufhcient width to surround the boss 7L of the driving wheel a in such manner that the lever u can lreely oscillate to and fro about its pivot t without coming in contact with such boss lt. rlhe lower ond 1 of the lever u terminates in a driving linger L whose surfaces 3 and 4 are inclined toward the stud r. Sometimes such surfaces, instead oi' being plain surfaces el, as shown at the right hand side of Figs. 2 and 3, are each formed with a spher ical recess 5, as shown at the left hand side of YFigs. 2 and 3, i'or the reception of a spherical washer 6. The other two arms 7 and 8 of the driving lever 7s are each furnished with a suite able boss 9, Fig. 3, provided with a bearing 10 that extends at a suitable angle to the center line A B. The two bearings 1() may be plain although they are preferably formed with screw threads 11 in which are mounted tubular sockets 12 and 13 the outer periph# eries of which are screw threaded at 14 for a certain distance in order to screw into the bearings l() and to be capable of adjustment endwise therein and be then secured in the desired position by locknuts 15 threaded on the screw threads 111 of the sockets and bearing against the ends 16 of the bosses 9.

The bore 17 of each tubular socket 12 and 13 is reduced in diameter at its outer end 18 thereby forming a shoulder 19 and a smaller hole or boring 2O which is` screw threaded at 21 and in which is screwed a hollow adjusting screw 22 that is formed with a head 23 to facilitate its operation and the en d 2e of which abuts against a washer 25 having a central hole 2G and which is located within the corresponding socket 12 or 13.

EXtending centrally through each socket 12 and 13 is a buffer bolt 27 the end face 28 of the head 29 of which is spherical and the shank or spindle 30 of which passes through the washer 25 and through an axial hole 31 in the hollow adjusting screw 22, the project; ing outer end of the bolt being threaded at 32 and having mounted upon it an adjusting nut 33. A helical spring 34 is threaded on the shank or spindle 30 of each buffer bolt 27, one end 35 of the spring bearing against the inner face 36 ol' the head 29 While the other end 37 abuts against the face 38 of the washer I The heads 29 of the buffer bolts are 25. thereby caused to press against the facesS and 4. of the driving linger' 2 and tend to maintain the pendulum lever u in its normal position. The springs 34 are capable of being compressed or allowed to expand in their sockets by turning the adjusting nut 33 in the proper direction, on the screw end 32 of the bufl'er spindle.

The buffer bolts 27 with their springs 34 are capable of endwise bodily movement in the sockets 12 and 13 upon manipulation of the hollow adjusting screws 22 5 the sockets can also be readily adjusted endwise in their bearings so as to always insure the heads of the buffer bolts being in the requisite position in relation to the driving linger 2 of the pendulum leveru so as to absorb and prevent any shock being transmitted to the driving wheel.

W hen the driving wheel a is commencing toV rotate say clockwise for example, it moves the head e of the pendulum lever a in the same direction, the other end or driving finger 2 of the pendulum lever is thereby gradually moved toward one side and pushes the corresponding bul'fer bolt 27 and spring 34 into the socket 12 until the face 3 of the driving finger, either directly or through the washer 6 before mentioned, comes in contact with the end of the socket 12 and thereby transmits movement to the driving shaft Without shock, and, when the wheel is stopcping, the buffer arrangement moves the pen ulum lever to its normal position again also without shock. rlhe driving lever 7c, when used for driving in one direction only, may be rovided with only one s ring buffer and soc ret arrangement as wil be understood. 'lhe sockets 12 and 13 may each be furnished at its inner end with a square, hexagon or the like enlargement 39', as shown on the socket 12 in Fig. 2, to enable it to be readily turned for adjustment in its screwed bearing; or the inner ends thereof may be plain, as shown on the socket 13 in Fig. 2, and their outer ends L10 be suitably formed to facilitate the operation of turning them for adjustment in their bearings.

Instead of the gear driving wheel illustrated, a driving pulley or the like may in like manner be constructed with the improved shock absorbing devices described.

Instead of the wheel rotating on the sleeve of the driving lever it may in some cases be mounted to rotate on the shaft.
